asp.net中网格视图中的链接按钮 [英] link buttons in grid view in asp.net

问题描述

我使用asp.net中的链接按钮通过其rowcommand属性处理事件，但它始终在其e.CommandArgument
中显示"(空)值
这是我的代码:

I m using link button in asp.net for handling their event i m using its rowcommand property but it always shows "" (null) value in its e.CommandArgument

this is my code:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" 

            DataSourceID="SqlDataSource1" DataKeyNames = "id" OnRowCommand = "GridView1_RowCommand">
            <columns>
                 <asp:TemplateField>
                    <itemtemplate>
                        <asp:LinkButton ID="LinkButton1" CommandName = "getid" runat="server" 

                            Text='<%# Eval("id") %>' CommandArgument='<%# Eval("id") %>'>
                    </itemtemplate>
                
            </columns>

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        TextBox1.Text = e.CommandName.ToString();
    }

字段eval("id")不为空.它包含整数值(1,2,3,4，...)

告诉我是否做错了什么

the field eval("id") is not empty. it contains integer values (1,2,3,4,...)

tell me if i m doing something wrong

推荐答案

像这样在行命令中替换

if(e.CommandName =="getid")
TextBox1.Text = e.CommandName.ToString();

replace in row command like this

if(e.CommandName=="getid")
TextBox1.Text = e.CommandName.ToString();

您的page_load是否包含

Does your page_load contains

if(!IsPostBack)
